This guide shows how to conduct a systematic risk assessment that satisfies EU directives and supports review-ready documentation.

This is backwards. Risk assessment should happen during design, when you can actually change the product to eliminate hazards. The risk assessment should influence enclosure design, thermal management, component selection, firmware safeguards, user interface design, and the content of your user manual. When risk assessment is done late, you end up adding warnings and labels to problems that could have been designed out. The pain point is not writing the document. The pain point is conducting the assessment early enough that it can influence design decisions, and documenting it thoroughly enough that it can survive scrutiny if authorities request your technical file. Requirements ## Hazard categories to consider ### Electrical hazards Electric shock, burns, fire from short circuits, exposed conductive parts, insufficient insulation ### Thermal hazards Burns from hot surfaces, fire risk from overheating, cold stress, thermal degradation of materials ### Mechanical hazards Moving parts, sharp edges, pinch points, falling objects, instability, crushing hazards ### Chemical hazards Toxic substances, battery leakage, off-gassing from materials, corrosive substances ### Radiation hazards RF exposure from radio equipment, optical radiation from LEDs, laser hazards, ionizing radiation ### Software hazards Incorrect operation from firmware bugs, safety-critical failures, cybersecurity vulnerabilities Process ## Step-by-step risk assessment workflow 01 ### Define intended use and foreseeable misuse Document who will use the product, how they will use it, in what environment, and what misuse scenarios are foreseeable. This defines the scope of your risk assessment. 02 ### Identify all hazards Systematically identify every potential hazard: electrical, thermal, mechanical, chemical, radiation, ergonomic, and software-related. Consider normal operation, fault conditions, and end-of-life scenarios. 03 ### Estimate risk for each hazard For each hazard, estimate severity of harm and probability of occurrence. Use a risk matrix to categorize risks as acceptable, mitigated with controls, or unacceptable requiring design changes. 04 ### Implement risk control measures Apply controls in order of priority: inherently safe design, protective measures, and user warnings. Document each control and how it reduces risk to acceptable levels. 05 ### Verify control effectiveness Test and validate that controls actually work. This may include safety testing, failure mode analysis, software verification, and user validation studies. 06 ### Evaluate residual risk After controls are implemented, reassess risk. Document residual risk levels and confirm they are acceptable. If not, implement additional controls. 07 ### Document everything The risk assessment must be documented in the technical file. Include hazard list, risk evaluation, controls implemented, verification evidence, and residual risk assessment. Structure ## Risk control hierarchy EU directives require applying risk controls in a specific order of priority. Relying only on warnings is insufficient—design changes and protective measures must be considered first. 01 Inherently safe design: Eliminate hazards through design choices (e.g., low voltage instead of mains, enclosed moving parts) 02 Protective measures: Add safeguards if hazards cannot be eliminated (e.g., thermal cutoffs, current limiting, guards) 03 User information: Provide warnings and instructions for residual risks that cannot be eliminated or sufficiently reduced ## Learn this properly, not just for one product In-depth courses and books that teach the process — not a one-off answer you'll need to look up again next time.

Risk assessment is a fundamental requirement under all CE directives. Even simple products must have a documented risk assessment showing that hazards have been identified and risks reduced to acceptable levels. ### What risk assessment method should I use for CE marking? There is no mandated method, but ISO 12100 (Safety of machinery) and IEC 62368-1 (Audio/video and information technology equipment) are widely accepted. The key is using a systematic, documented approach that can be defended. ### Can I copy a risk assessment from a similar product? No. Each product requires its own risk assessment based on its specific design, intended use, and hazards. You may use a similar assessment as a template, but it must be customized and validated for your product. ### How detailed must the CE risk assessment be? The assessment must be proportionate to the risk. High-risk products need detailed analysis with extensive verification. Low-risk products can have simpler assessments. The key is showing a systematic process and adequate documentation. [ Map your product, free Every standard, document, and test that applies — free, no account required.
